1 Claim.

The invention relates to new and useful improvements in a sheet metal shipping container for fishing rods and the like.

An object of the invention is to provide a container formed of body sections which are joined for closing the container s rigid container structure.

A further object of the invention is to provide a shipping container of the above type wherein one of the body sections is provided with an outwardly rolled strengthening bead at the open end thereof and a threaded section adjacent said bead, while the other section is provided at its open end with an inwardly rolled hollow bead and a threaded section adjacent thereto which is adapted to engage a threaded portion on the other section for joining the two sections into a single container.

In the drawing which shows by way of illustration one embodiment of the invention:

Figure 1 is a longitudinal sectional view through a container embodying the improvements;

Fig. 2 is an enlarged sectional view through the open end of one of the body sections;

Fig. 3 is an enlarged sectional view through the open end of the other body section;

Fig. 4 is a sectional view on the line 4-4 of Figure 1;

Fig. 5 is a sectional view on the line 5-5 of Figure 2; and

Fig. 6 is a detail showing a portion of the open end of one of the sections prior to the threading and flanging of the same,

The sheet metal shipping container as illustrated includes two body sections A and B. The body section B is made from sheet metal which is rolled into cylindrical form and the edge portions united by a side seam. The side seam in the region indicated at l is in the form of a lock seam, that is, it includes inter-engaged hooks which are bumped tightly together for holding the edges of the body blank in a fixed position relative to each other. The edges at the upper section 2 of the body are merely lapped. This is to facilitate the beading and the forming of screw threads in this portion of the body section. The two body sections A and B, so far as the side seams are concerned, are similar in construction The body section A after it is formed into cylindrical shape and the edge portions united by the side seam, is flanged in the usual manner, and then a closure end 3 is secured thereto by a double seam 4. The open end of as to provide a single hollow bead 5. The body wall is also rolled inwardly to form a beaded portion 6. In between the beaded portion 6 and the hollow bead 5, the body wall is shaped to provide screw threads I. The hollow beaded portion 6, the screw threads, and the hollow bead 5 are all formed in the body wall where the edge portions are lapped, and this greatly facilitates the passing of the beading roll and threading roll across the side seam. In order to secure the lap sections and hold them in place, the outer end is solder-bonded'as indicated at 8 in Figure 6.

this body section A is rolled outwardly into a The body section B after it is formed into cylindrical shape and the edges joined in a side seam, is flanged in the usual manner, and then the closure end 9 is secured thereto by a double seam Id. The open end of this body section B is rolled inwardly to form a hollow bead II. It is also beaded outwardly so as to provide a beaded portion I 2 which serves as a stop shoulder. In between the hollow bead H and the outwardly projecting beaded portion l2, the body wall is shaped to form screw threads l3. These screw threads are so dimensioned as to cooperate with the screw threads 1 in the securing of the two sections together, and when one section is threaded on to the other, the outwardly projecting beaded portion [2 and the inwardly projecting beaded portion 6 serve as stop shoulders so that the hollow beads 5 and II contacting therewith, respectively, will yield and thus produce a very firm union between the two body sections. In other words, when the hollow bead 9 contacts with the shoulder B, there is sufiicient yielding of the parts to permit the hollow bead 5 to come in contact with the shoulder l2, and thus we have two tight locking regions which makes a very firm union for the body sections and enables said body sections to be made relatively long for the housing of the fishing rods and similar articles. The open end of the body section B has a similar lap seam and solder bond for joining the edge portions in the region where the body is curled, beaded and screw-threaded.

It is obvious that minor changes in the details of construction may be made without departing from the spirit of the invention as set forth in the appended claim.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent, is:

A sheet metal shipping container for fishing rods and the like comprising cylindrical body sections, each having one end thereof closed by an end member seamed thereto, the other end being open, the open end of one of said body sections being rolled outwardly into a hollow bead and having an inwardly beaded portion forming a stop shoulder, said body section between said outwardly rolled bead and said inwardly beaded portion being shaped to provide a screw thread, the other section at its open end being rolled inwardly to form a hollow bead. and having an outwardly beaded portion forming a stop shoulder, said body section between said inwardly rolled bead and said outwardly beaded Ill portion being shaped to provide a screw thread adapted to enter vthe screw thread on the other section for joining said sections and closing the container, each body section having a side seam including interlocking hooks extending from the beaded portion in the body wall to the closure end therefor, and lap sections extending from said interlocked hooks to the open end of the container, which lap sections are solder-bonded at WILLIAM H.
